VMware Date store monitoring using multipile condition

[sgoffar]

Hi Team,

We got a request from a customer to monitor the VMware Datastore and alert based on below condition.

Can you please help on this.

Multiple conditions should be met to trigger the alert.

Warning: If Free Space < 5% and Free space is < 100GB

Critical: If Free Space <2% and Free space is < 20GB

If you define the warning threshold like this ($ARG6$) to

Code: Select all

datastore_free:100,datastore_free%:5

and the critical threshold like this ($ARG8$) to

Code: Select all

datastore_free:20,datastore_free%:2

Try that and see if it works like you want.

Thanks for the input by giving the value as suggested we are getting below value.

COMMAND: /usr/local/nagios/libexec/check_by_ssh -E 1 -t 90 -l vi-admin -H 172.XX.XX.X -C "~/box293_check_vmware.pl --timeout 90 --server 172.XX.X.X --check Datastore_Usage --name \"DAL-VDI-NFS-APPVOL\" --reporting_si \"Disk_Size:GB\" \"--warning\" \"datastore_free:100,datastore_free%:5\" \"--critical\" \"datastore_free:20,datastore_free%:2\""
OUTPUT: OK: Datastore 'DAL-VDI-NFS-APPVOL' {Free Space: 1,012.8 GB} {Used Space: 58.2 GB} {Capacity: 1,071 GB}|'Free Space'=1012.8GB;100;20 'Used Space'=58.2GB 'Capacity'=1071GB [Datastore_Usage]

But Is it calculating the % ??

Also on $ARG4$ is the value will be like: Disk_Size:GB as it is. Or needs to update something here also.

You should go to the link below and take a look at page 28 of the manual, to get the percentage thresholds to function, the command will have to be edited by adding the --perfdata_option option.
https://exchange.nagios.org/directory/P ... re/details
The settings I posted earlier will have to be edited to make the percentage thresholds function the way you want.

Thanks a lot for inputs. Now it's working for warning. For critical I needs to add two more Argument.

As attached image , I needs to add 10 Argument currently it's 8 Argument.

Can you please help me on this.

[tgriep]

What you can do is to put all of the separate arguments into one argument and that will free up the $ARGx$ slots so you can add more options to the command.
Arguments do not have to be separated, they can be one long line.

So, what you could do is copy $ARG6$ and paste it on the end of $ARG5$ with a space between it and then copy $ARG7$ and paste it on the end of $ARG5$ with a space between it and so on.
Then you will be able to add more arguments to that check.

The suggested option is not working we are getting below error.

Change the $ARG5$ field from

Code: Select all

--perfdata_option

to

Code: Select all

--perfdata_option Datastore_Free:1,Datastore_Free%:1,Datastore_Capacity:1,Datastore_Used:1,Datastore_Used%:1

Then delete everything in the $ARG6$ field and see if that works for you.

If you are using the Test Check Command button, that sometimes causes problems, you should save the settings and go to the Home > Service details screen and see if the command works.

If you want to test the command, you can run this from the command line on the XI server so you can edit the options to get the output you want and then change it in the XI Core Config Manager.

Code: Select all

We are getting same error.

I simplified the command a little to see if it works. Try running this in a root shell on the Nagios server.

Code: Select all

/usr/local/nagios/libexec/check_by_ssh -E 1 -t 90 -l vi-admin -H 172.26.171.249 -C "~/box293_check_vmware.pl --timeout 90 --server 172.26.171.40 --check Datastore_Usage --name "DAL-VDI-NFS-APPVOL" --reporting_si "Disk_Size:GB" "--perfdata_option Datastore_Free:1,Datastore_Free%:1" "--warning datastore_free:100,datastore_free%:5" "--critical datastore_free:20,datastore_free%:2""

It it still fails, add the verbose option to the command and post the output here.
To add the verbose output, you would add a -v to the end of the command.
